IM I ROVEMENT IN SNOW-GUARDS FOR ROOFS.

Specification forming part of Letters Patent No. 186,996, dated February6,1877; application filed January 13, 1877.

To all whom it may concern Be it known that I, GEORGE F. FOLSOM, ofBoston Highlands, in the county of Suffolk and State of Massachusetts,have invented a new and Improved Snow-Guard for Roofs, of which thefollowing is a specification Figure l is a section of a roof having myimproved snow-guard attached, taken on line Fig. 2 is a plan view. Figs.3 and 4 are detail views of parts of the snowguard.

Similar letters of reference indicate corresponding parts.

My invention relates to an improvement in snow-guards for roofs; and itconsists of a wire bent at right angles at one end and sharpened, so asto be readily driven into the roofboards, and at the other end it isbent in the opposite direction, and formed into a loop of peculiarshape, which projects upward from the roof, and is provided with atongue, which is capable of retaining a plate of metal, or an ornamentalmetallic leaf.

The object of the invention is to provide a guard for roofs that willretain the snow until it melts, thereby preventing the sliding of largequantities of snow in a mass from the roof.

Referring to the drawing, A is a guard formed of wire of a suitable sizeby bending itrat right angles at a, and flattening and sharpening it atthe end thus bent, so that it maybe readily driven into the boards ofthe roof. The wire isalso bent at right angles at b, in

' a direction opposite to that just mentioned,

andis formed into a loop, 0, and is still further bent to form a tongue,d, which extends upward across the loop 0, as clearly shown in Fig. 3.

The guard thus formed is secured to the roof by driving the end a, intothe roof-boards in the joint'between the shingles or slate, so

The number of guards used on a roof is governed by its pitch orinclination, a steep roof requiring a greater number than one of lessinclination.

The guards not only answer the purpose of retaining the snow, but theyalso serve as holds for the staging used in applying the slate. Theyalso afford a means of climbing over roofs in case of tire.

On a very steep roof the guards should be connected by a wire, whichafi'ords an additional means of holding the snow, and, when suitablyconnected with the earth, the guards and connecting-Wires might answerthe purpose of lightning-conductors.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.,A snow-guard for roofs, consisting of a wire bentoppositely at right angles at its ends, having one of its ends flattenedand sharpened, and having its other end formed into a loop and tongue,substantially as herein shown and described.

2. The combination of the guard A and plate f, substantially as hereinshown and described.
